Naturally triggered gliding-snow and loose-snow avalanche activity

Naturally triggered gliding-snow and loose-snow avalanche activity

Avalanche danger above the timberline is moderate, below that altitude danger is low. Glide-snow and loose-snow avalanches can trigger naturally in some places on very-to-extremely steep slopes and in isolated cases grow to large size. Avalanche activity will increase during the afternoon hours due to solar radiation. Above 2000m the fresh drifts are prone to triggering and can be triggered even by minimum additional loading. Releases will remain small, in isolated cases medium-sized.

By Sunday midday, 30-50cm of fresh snow at high altitudes. Prior to the snowfall, sunny slopes were bare of snow by and large, shady slopes were often thoroughly wet. Inside the drifts, trigger-sensitive weak layers can rapidly form.
